rlliis invention relates to printing devices customary of that class which are adapted to be stored prevented in accordance with a card index system and clamping to be run through addressing or rother machines for printing.

It is customary to provide these devices with kee ers adapted to receive removable index ta s and it is important that avoid cutting the tabs should be held rigidly in fixed posikeeper, tion in the keepers and also that they should facture, and utilizing the metal heretofore be easily insertable and removable. These out out to form lips for supporting and printing devices are subject to frequent ex- ,protecting the tabs above the keeper. amination in the storage drawers, they are I have selected for illustrating the invenoften removed from the drawers and han tion in the accompanying drawings a metal dled separately for various purposes, they plate printing device having printing charare deposited in the magazine of an addressacters embossed thereon but I do not re-v ing machine a drawer full at a time and run through the machine one at a time, and bodiment `asit may be used with other print- :for which it is or may be taining means andV eectiveengagement of the stem with the locking stud being thereby printing preserved.

This result occurs, as I believe beparallel ,with the top edge of cause thekeeper permits the tab to be bent 'panel is joinedwith the plate at its. top edge too close to the end which engages the retainby the spaced connections 9 and at its boting stud and also because there is no support for the stud above the keeper panel to prevent between these connections the panel is tree the tab from being bent over the panel. from the body ofthe plate. Lips 11 are My invention has for its object to provide. formed on the upper Ledge of the panel bemeans for-holding a tab rigidly and securely v tween the connections 9 and these lips project on a'printing device and at the same time permit it to be readily inserted and removed.

This above the panelparallel with vthat part of i upper edge of the panel and project upwardv1y in or about the plane of thc panel and parallel with the upper edge portion of the plate and nearly as high as the top of the plate. Lips -12 are provided on the back of the plate at the bottom of the panel and between the keeper connections 10, and studs 13 are punched in th-e plate opposite these lips. The tab 14 may be-of any suitable kind having a stem 15 provided with an opening 16 near its free end to receive the stud 13. The stem is preferably provided with a rib 17 extending longitudinally to strengthen the stem and to aid in efecting clamping engagement with the keeper. The construction provides a slot 18 at the top of the keeper panel and close to the top of the printing device, and a slot 19 at the bottom of the panel and close. to the stud 13. These slots arearranged in vertical alinement and they i are formed by cutting the plate and pressing the panel outward from the body of the plate without removing any metal. These slots are adapted to receive the stem of the tab which is inserted therein with a straight downward thrust and is bent only sulicient at its lower end to engage the stud 13. The tab is then held in upright position by engagement at its back with the lip portion 12 and the top edge portion 20 of the plate and by engagement at its front with the keeper panel 8. The keeper is slightly curved transversely, Fig. 3, which has the effect of forming an effective bearing to clamp the stem of the tab. The bottom end of the stem is shown slightly sprung away from the body of the printing device, Fig. 3, which is due to the fact that the opening 16 in the stem is preferably a trifle less in size than the greatest size of the stud and the lower end of the stem will normally lie in the sprung position so that it will not stick on the stud but will slide thereover when the tab is pulled in a normal way out of rthe keepers.l The top edge of the lip 11 which forms one wall of the slot 18 is in substantially the same plane as the edge 21 y which lforms the opposite parallel wall of remove it from 'the the slot to cause that vcidental 'displacement the slot and these walls are close together forming a narrow slot to freely receive the tab, but the tab cannot move suiciently in part of the stem-in the keeper to-bend sufficiently to enable acof the tab from the printing device. And while the tab is thus securely -held against accidental displacement a sufficient straight pull maybe exerted `on the tab to release it from the stud and printing device. The slots 18 and 19 correspond in length closely to the width of the tab stem freely andto hold the tab 'upright therein against lateral movement. As many alined pairs of slots are provided as may be required and as the length of the keeper stem to receive the` panel will tions on the printing device.

My invention is simple in character but it performs the veryuseful and important function of preventing displacement of the tab from the printing device accidentally or due Y to 'careless or rough handling of the printing device. The lip 11 constitutes a guide to receive the end of the t'ab and facilitates the insertion of the tab in the printing device. It has been the practice heretofore to punch out slugs of metal in forming a continuous offset panel on the plate With top and bottom slots to receive the tab and it has been necessary to Vkeep the punching tool sharp to provide smooth edges at the slots to permit ready insertion and removal of the tabs. In the present invention the slots are formed by a shearing action and since no slugs are punched out it is much easier to keep the tools in proper working condition.

I have described the invention in a simple form as embodied ina one-piece printing plate but I do not limit the invention to this embodiment' and reserve the right to make all such changes in the form, construction and arrangement of parts as may be necessary or desirable for adapting the invention for other printing devices or for other purposes within the scope of the following claims.
